How it Works

Our straw bale granny flats use straw bale panels which are 255mm wide.  One side is clad, the other side is rendered. 

STEP 1 Choose your size:

a) 34m2 granny flat
b) 60m2
c) custom, use your own design

The fastest, most affordable option is our design because it’s been tested and
Yes you can change the internal layouts of our designs. 

STEP 2 Choose how you want it built:
a) We send you all of the materials as a kit (you build it DIY as an Owner Builder or with your Builder)
b) We build it for you

STEP 3 Choose your finish:
a) Clad or render on the exterior walls
b) Clad or render on the interior walls
c) External walls clad and the interior walls earth renders (easiest, fastest and most affordable option)

The panels come shipped to site with ply on one side and 1 coat of render on the other side as the standard most affordable option

STEP 4 Do you need to learn how to build it?
